Certificate of Authorization Cost and Renewal Calculator
A professional corporation needs its regulator’s certificate as well as its incorporation, and the certificate has to be renewed. Work out your next deadline, what the corporation costs to keep each year, and why a lapse is a different kind of problem from a late filing.

Disclaimer: The fee fields on this page are blank or placeholder values for you to replace, not quoted amounts. Certificate of authorization application fees, annual renewal fees and any late or reinstatement charges are set independently by each regulatory college or body, differ between professions, and are revised from time to time; the only reliable figure is the one published by your own regulator or stated on your invoice, and it must be confirmed there. Government incorporation fees and name search costs are likewise set by the registry and change. The renewal date produced here is calculated arithmetically from the month and day you enter and is not taken from any regulator’s records; your certificate, your regulator’s portal or your renewal notice is the authoritative source, and some regulators tie renewal to the member’s own registration cycle rather than to the certificate’s issue date. Eligibility to incorporate professionally, who may hold voting and non-voting shares, whether family members may hold any shares at all, director and officer requirements, permitted corporate names and the activities the corporation may carry on are governed by the relevant professional statute, regulations and college by-laws, and differ substantially between professions; a structure permitted for one profession may be prohibited for another. Advice on those requirements is legal advice, which chartered professional accountants do not provide. Practising through a corporation whose certificate is not in good standing raises regulatory questions, and potentially questions about billings made during that period, which are matters for your regulator and for legal advice rather than matters this page can quantify; nothing here should be read as an assessment of consequences in any particular case. A professional corporation also has ordinary corporate obligations, including tax returns and corporate filings, which continue independently of the certificate. This page is general information, not legal, tax or accounting advice.
Two Registrations, Two Clocks
A professional corporation is two things at once. It is a corporation, registered with the provincial registry and filing tax returns like any other. It is also an authorised vehicle for practising a regulated profession, which requires a certificate from your own college.
Those run on separate clocks, administered by different bodies, with different consequences for letting one slide. Owners who keep the tax filings immaculate routinely forget the certificate, because nothing about the tax side reminds them of it.
The corporation does not stop existing if the certificate lapses. It stops being authorised to practise through, which is a different and more serious problem than a corporation that is merely behind on filings.
Why a Lapse Is Not Like a Late Tax Return
A late corporate return produces interest and a penalty, both calculable, both payable, and the matter ends. A certificate that has lapsed is a regulatory matter, and the questions it raises are not financial ones.
Whether practice carried on through the corporation during the gap was properly authorised, and what that means for billings made in that period, are questions for your regulator and, if it comes to it, for a lawyer. They are not questions with an arithmetic answer, which is precisely why this page does not try to give one.
The practical advice is unglamorous. Put the renewal date in the same calendar as everything else that matters, with a reminder a month ahead, and treat it as seriously as a tax deadline. Most lapses are administrative rather than deliberate.
The Rules Differ by Profession, Substantially
This is where general advice becomes useless. Who may hold shares, whether family members may hold non-voting shares at all, what the corporation may be called, who must be a director: these are set by each profession’s statute and college by-laws, and they genuinely differ.
Arrangements that are standard for one profession are prohibited for another. Anyone telling you what professional corporations can do without first asking which profession is not giving you advice worth having.
| Question | Where the answer comes from |
|---|---|
| Who may hold voting shares | Your profession’s statute and by-laws |
| Whether family may hold non-voting shares | Differs by profession, do not assume |
| What the corporation may be named | Your college’s naming rules |
| What fee applies | Your college’s current schedule |
| When renewal falls due | Your certificate or renewal notice |
Income Splitting Is Not What It Was
Family members holding non-voting shares was once a straightforward way to split income, and it is the reason many professional corporations are structured the way they are. The rules on split income changed that substantially, and dividends to family members who are not meaningfully involved in the business are frequently taxed at the top rate regardless of the share structure.
Where a structure was built around a splitting strategy that no longer works as intended, it is worth revisiting rather than assuming it still does what it was set up to do.
What the Corporation Costs Every Year Regardless
The certificate renewal is usually the smallest recurring item. The corporate tax return and financial statements dominate the annual cost, and the corporate filings and minute book maintenance sit underneath.
That total is worth knowing before incorporating, because it is the figure the tax saving has to beat. A professional corporation that saves less in tax than it costs to run is a common and avoidable mistake.
Whether to incorporate at all is the prior question. The setup cost calculator covers establishing one, and the profession-specific calculators work out whether the tax saving justifies the running cost in the first place.
What This Calculator Does Not Do
- Quote any regulator’s fees, which you must confirm with them
- Read your renewal notice, which is the authoritative date
- Decide who may hold shares, which is a legal question
- Assess a lapse, which is for your regulator
- Cover member registration, which is separate from the corporation
- Confirm eligibility to incorporate in your profession
